Answer: 1- 9
2-36
3-81
Step-by-step explanation:
If there were 49 cars in a line that stretched 528 feet, what is the average car length? assume that the cars are lined up bumper-to-bumper
Answer: We are given there are 49 cars
Also these 49 cars are in a line stretched 528 feet.
Now the average length of the car is:
Average length = 
=
Therefore, the average length of car is 10.78 feet
12 x 6s - 8 x 4s = 72s - 32s = 40s
Answer: <u>3 hours and 20 minutes</u>
Step-by-step explanation:
3x + 2(3)x = 30
3x + 6x = 30
9x = 30
9/9 = 30/9
x = 3 1/3 hours
Slope = (y2-y1)/(x2-x1)
(3+1)/(2-0) = 4/2 = 2
The slope is 2
